An assessment tool for the appropriateness of activity-based travel demand models
… or implementing activity-based travel demand models to forecast future travel patterns. The proclivity towards operating activity-based models is the capability to model disaggregate travel data to better understand the model results that are generated with respect to the latest …

Probabilistic seismic demand models of RC bridge columns retrofitted with shape memory alloy spirals
… for SMA retrofitted columns by creating seismic demand models which relate the intensity measure (IM) of an earthquake with the demand imposed by the earthquake on SMA retrofitted RC columns, which is quantified in terms of demand measures (DM). An array of vulnerable RC bridge columns, …

Probabilistic capacity and seismic demand models and fragility estimates for reinforced concrete buildings based on three-dimensional analyses
… The fragility estimates are conducted using the demand and capacity models typically for the 3D responses. The demand models expressed in terms of drift are developed as functions of the spectral accelerations in the two planar directions. The demand prediction is compared in a probabilistic …

Analysis of Social Equity in Transportation in Washington DC Region Considering Sea Level Rise Using Advanced Travel Demand Models
… high-fidelity agent-based, activity-based travel demand model to produce travel times to employment centers. This travel time is used as a proxy to access to opportunities. The results are visualized in a GIS heatmap. The model is applied to the Metropolitan Washington DC area. This manuscript …

Predictive demand models in the food and agriculture sectors : an analysis of the current models and results of a novel approach using machine learning techniques with retail scanner data
… unreliable information, about the future of demand and available historical data. Consequently, the lack of an appropriate understanding of what is the actual food consumption trend, lead's the producers in some cases to make wrong bets, which eventually causes food waste, price volatility …

Modeling Daily Power Demand in Southern Kentucky: A Single Household Approach
… regression (LOESS), to forecast a 24 hour demand profile at the household level and compare it to existing aggregate demand models discussed in literature. Of these aggregate demand models, a quadratic autoregressive model was selected to be used as a basis for comparison with the LOESS …

Essays on Dynamic Demand Estimation
… consists of three chapters relating to dynamic demand models of storable goods and their application to taxes that are imposed on soft drinks. Broadly speaking, the first chapter builds the estimation strategy for dynamic demand models of storable goods that allows for unobservable heterogeneous …

Predicting Ridership and Travel Time Impacts of Bus Service Changes Using Sketch Planning Methods
… of bus service changes, with a focus on direct demand models and the use of an open-source multimodal routing algorithm. The framework is designed to be streamlined with the use of data sources and capabilities, such as exporting a General Transit Feed Specification (GTFS) feed of a given bus …

Forecasting the use of new local railway stations and services using GIS
… with the<br/>potential to enhance local rail demand models have been identified. Trip rate and trip end<br/>models have been developed which are capable of forecasting usage at new station sites<br/>anywhere in England and Wales. Geographically Weighted Regression (GWR) has been<br/>used to …

Decision Support Models For The External Variety Of Configurable Products
… In this study, we developed decision support models that can help decision makers when using operational models to manage external variety of configurable products. Our main objective is to reduce the number of product variants offered in a proper way so that inventory and demand models do not …

Tractable multi-product pricing under discrete choice models
… prices under the basic multinomial logit (MNL) demand model. Linear constraints can induce a non-convex feasible region. Nevertheless, we show how to efficiently solve the pricing problem under three important, more general families of demand models. Generalized attraction (GA) models broaden …

Proposta metodológica para avaliação da demanda residencial de energia elétrica através do desenvolvimento de uma curva de carga horária
The growing electricity demand combined with the emerging power generation technologies have increased the importance of electric power demand models for the electric planning. In that way, demand side management (DSM) measures are being used more often, in order to guarantee de safety and …

Structural Change in the Retail Demand for Beef, Chicken and Pork: An Application of Gradual Switching Regression (Segmented Regression, Varying Parameters)
… a structural change has occurred in the retail demand for beef, chicken and pork. In particular, two gradual switching regression (GSR) demand models--one which allows a permanent change in income and own-price elasticities and one which allows a permanent change in income, own-price and …

Methodik und Prozessgestaltung strategischer kommunaler Verkehrsplanungen : Anwendungsmöglichkeiten von systemdynamischen Modellen zur Bewertung kommunaler Verkehrsstrategien in der Planungspraxis
… implementation. The downside to popular traffic demand models is that they only represent the impacts of structural and operational measures in the fields of road traffic and public transport. But the arrangements of supply-side measures, as e.g. bike and pedestrian traffic, consultant and …

The effects of minimum wage increases on labor demand growth
… of conditional and unconditional labor demand models, as well as the panel structure of the Colombian Annual Manufacturing Survey (AMS). Findings show significant long-run minimum wage elasticities in labor demand: 0.638, -0.774, and -0.6 for skilled, unskilled, and total workers, …

Joint Hedonic Travel Cost Method: Combining Revealed and Stated Preference Data to Estimate Demand for Attribute Quality of Sport Fishing in Illinois
… implicit prices. The hedonic travel cost models are specified by combining hedonic price functional forms (linear, semilog) and data types (revealed, stated, pooled data). Prior to the estimation of the joint models, the revealed and stated preference models are statistically tested to …

A life-cycle flexibility framework for designing, evaluating and managing "complex" real options : case studies in urban transportation and aircraft systems
… was completed. System dynamics and traffic demand models were used to quantitatively evaluate flexibility for each case study. Forty interviews with practitioners were conducted to better understand the practical challenges associated with flexible systems.

Water demand management in Kuwait
… limited access to water resources. Yet water demand per capita is much higher than in other countries in the world, estimated to be around 450 L/capita/day. There are several reasons for such a high demand, but one is certainly the price. Water does have its pricing schedule in Kuwait, but in …
